The GOE and the Rise of Aerobic Bacteria: Tracing the Oxygen Revolution in Earth’s History
Introduction: Why aerobic life mattered The Great Oxidation Event (GOE) marks a turning point in Earth’s history, when atmospheric oxygen began to accumulate after photosynthetic microbes reshaped the climate and chemistry of the planet. This oxygenation set the stage for a dramatic lineup of evolutionary innovations, especially the rise of aerobic (oxygen-using) bacteria. Understanding when…

Sped-Up Microbial Evolution Could Help Gut Health, UCLA Study Finds
New Insight into How Our Gut Microbiome Establishes Itself Every person hosts a bustling community of microbes in the gastrointestinal tract, far outnumbering human cells. This gut microbiome influences digestion, immune function, and even brain health. While some microbes produce vitamins and antioxidants, others simply occupy space, crowding out potential pathogens. Understanding how this microbial…

Sped-Up Bacterial Evolution in the Gut: UCLA Study on DGRs and Microbiome Colonization
Overview: A Faster Path to Gut Colonization Every person hosts a vast, vibrant community of microbes in the gastrointestinal tract. This gut microbiome plays a key role in digestion, immune function, and even brain health. A UCLA-led team has unveiled a mechanism that could explain part of how these microbes establish themselves more rapidly in…
